PORTABLE LBBJCANT OIR GREASE CUP FILLER.

Application filed April 26, 1924.

rily for filling the lubricant or grease cups employed in connection with the bearings between the connecting rods and crank pins of locomotives for which a relative large body of lubricant or grease is necessary, but it is to be understood that a filling device in accordance with this `invention can be employed for any purpose for which it is found applicable, and the invention has for its object to provide, in a manner as hereinafter set forth, a filling device having means for detachably connecting it with the cup and adapted to contain a body of lubricant or grease and further having means whereby such body can be quickly forced into the cup to lill the same for lubricating purposes, after which the device is disconnected from the cup and the latter is then closed.

Further objects of the invention are to provide, in a lmanner as hereinafter set forth, a portable lubricant or grease cup filler, which is simple in its construction and arrangement, strong, durable, compact, thoroughly efficient and convenient in its use, readily assembled and comparatively inexpensive to manufacture.

lWith the foregoing and other objects in view, the invention consists of the novel construction, combination and arrangement of parts, as hereinafter more specifically de-` scribed and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but. it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claim hereunto appended.

Figure iis a vertical sectional view, upon a reduced scale of a modified form of filler.

Figure 5 is a fragmentary view, in vertical section, of the form shown in Figure 4: and taken at right angles thereto.

Figure 6 is a section on line 6-6, Figure Referring to the drawings in detail, 1 indicates conventionally a lubricant or grease cup arranged in operative relation with respect to a bearing 2. The cup 1 is shouldered on its inner face, as at 3, and also interiorly threaded, as at 4. Although not shown, the cup 1 is to be closed by a removable plug or cap which threadedly engages with the threads Il. When the lubricant or grease is to be supplied, the cap is removed and the filler detachably engages with the threads 4. As the cap formsl no part of this invention, it is thought unnecessary `to, show the same.

Referring to Figures 1 to 3, the portable lubricant or grease cup filler, in accordance with this invention, comprises a tubular body portion 5, having a reduced peripherally threaded inner terminal portion 6 for threadedly engaging with the cap l, whereby .the filler will be detachably con nected in position for the purpose of supplying lubricant or grease.

The tubular body portion 5, in close proximity to the reduced inner terminal portion 6, is formed with a laterally extending rectangular opening 7, which is employed for the purpose of inserting the body of lubricant or grease into lthe body portion 5, so that the body of lubricant or grease can be forced into the cup 1.

The tubular body portion 5 is set up of two different` inner diameters, that portion of smaller inner diameter indicated at 8, and the portion of larger diameter at 9. The providing of the tubular body portion 5 of two different inner diameters forms a shoulder 1.0 at the outer terminus of that portion 8 of smaller diameter.` The opening 7 lcommunicates with the portion 8 of smaller ameter.

Snugly engaging the wall of the portion 8 of smaller diameter is a plunger 11 of a length to extend into the portion 9 of larger diameter. Secured to the inner end of the plunger 11 is a washer element 12 of any suitable material, and said element 12 rides against the inner tace of the body portion at the part ot smaller inner diaineter thereof. The washer 12 is secured in position by a hold-rast device 13. rhe outer end ot the plunger 11 is provided with a laterally extending annular liange or head 11, ot materially greater diameter than trie diaineter et the portion 8, but slightly less in diameter than the diameter oit the portion E).

The head 14Y oit the plunger 11 is termed with a pair ott outwardly extending spaced semi-circular lugs 15, and surrounding the plunger 11 and interposed between the head 1li and shoulder 10 is a coiled spring lo which normally inaintains the plunger 11 in a retracted position.

The plunger 11 is shitted Ytor the purpose of forcing the body ot' lubricant or grease troni the body portion through. the inediuin o'li a inanually operated u pivotally supported troni tl e body port in and slidabiy connected to the lugs '1`he cani is indicated at 1.7, is substantially semi-circular in contour and toi-ined with a segmentalshaped slot 18. rllhe cani 13.' is 'ded with a polygonal-shaped opening 19 disposed eccentrically with respect thereto. The cani 17 extends between the lugs 15 and is slidably connected therewith by a pin 20, which is inounted in the lugs and extends through the slot 1S.

Journalled in the tubular body portion 5 is a pivot 'for the cani 17, and said pivot consists ot a substantially elongated bar provided with an elongated cylindrical portion 21, a polygonal-shaped portion 22, a cylindrical portion 23 and a threaded portion 21;. The cylindrical portion 21 has its outeiI end provided with a head 25, which ahuts against the periphery ot the tubular body portion 5. The peripherally threadedL portion 2st carries a nut 2G which abuts against the periphery ot the tubular body portion 5 and in connection with the head` secures the pivot, tor the cain 17, to the tubular body portion 5. The portions 21 and 23 are journalled in the tubular body portion 5, and the polygonal portion 22 ein tends through the polygonal opening 19 so that when the cani 1T is shifted the pivot will be carried therewith. The polygonal portion 22 terminates in the cylindrical portion 23 and in connection with the latter provides a shoulder 27, against which abuts the can) 17.

Formed integral with the cani 1'? and prw jecting outwardly therefrom, is a lever arin 28 which facilitates the inanual operation oit the cain 17 :tor the purpose of shitting the plunger 11 to expel the lubricant or grease itroin the tubular body portion 5. To pro vide a clearance tor the cani 17 and lever 2S, the tubular body portion 5 is termed with a lengthwise extending slot 29 ot substantial length. Villien the lever arni 28 is shifted in a. clockwise direction, the curved edge 30 oit the cani 17 will ride against the outer tace ot the head 141, (see dotted lines in Figure whereby the plunger 1l will be moved inwardly to expel lubricant or grease. "i1/*hen pressure released on the lever 28, the action oit the spring 16 will shiit the plunger` 11 to retracted position.

1u the 'l'orin shown in Figures 1l; to the tubular body portion is indicated at 31 and is 'torined with a reduced peripherall),7 threaded inner terminal portion 32 tor the purpose or" detachably connectn'ig ine body portion 31 with the cup 1. 'Ehe here ot the body portion 31 is oif the saine diameter throughout. Vlhe body portion 31, in proximity to its reduced inner terininai 32, is Alornied with a rectangular opening 3st tor the purpose ot positioning the body ot lubrirant or grease in thty bore 33. The body portion 31 is turtherniore provided with a substantially elongated slot positioned outwardly with respect to the opening 31, and the latter and the slot conununicate with the bore Operating in the bore 33 is a plunger 35, whichy is normally in a retracted position. The plunger 3G is cylindrical, snugly enf) the wall ot the bore 33 and has secured to its inner end, by the hold-tast device 37, a washer 33 ot any suitable material.

The plunger 36, intermediate its ends, is termed with a lengthwise extending slot 3S), and said plunger 36, at right angles to tue slot 39, has its periphery torined with lengthwise extending grooves L10, projecting to the outer end ot the plunger 36 and said grooves l() have their outer ends closed by a dish 4:1, secured to the plunger 3G, as at 4t2.

The plunger 3G is shifted troni retracted position through the inediuin ot a rotative cani ot circular contour and the said cani L13 is torined with an eceentrically disposed polygonal opening 4141. rlhe diaineter ot the cani 13 is materially greater than the dialneter ot the bore 33, and said Cain 43 extends into the slot 35, the latter providing a clearance therefor. The inner tace ot the body portion 31 is grooved, as at 15, which also provides ay clearance tor the cam See Figure L1.

rlhe cain L13 is actuated through the inediuin oit a rotative spindle or shait torined ot a polygonal-shaped interniediate portion 1G und a pair of cylindrical end portions 4:7, 4S, which are journalled in the body portion 31. rllhe intermediate portion #liti extends through the polygonal-shaped opening L14- in the disk 113, so that when the spindle or shaft is revolved, the cani 43 will be carried therewith` The end portion 1-7 projects :troni the body portion 31 and is provided with a Cotter pin 19. The end portion 48 shaft.

The plunger 3G is normally retain-d in retracted position through the medium of a pair of coiled springs 52, which are mounted in the grooves and are interposed between the disk 4l and the polygonal-shaped portion 46 of the spindle.

The cam 43 is revolved to shift the plunger 3G inwardly to expel lubricant or grease against the action of the springs 52, and when the cam 43 is operated it rides against the end wall 53 of the slot 39, and owing to the fact that the cam 43 is eccentrically mounted, it is obvious that the plunger 86 will be shifted inwardly from its retracted position. When the spindle is released, the action of the springs 52 will force the plunger to its normal position.

'lhe normal position of the plungers ll and 36 is outwardly with respect to the openings 7 and 34 respectively, so that the plungers will not interfere with the positioning of the body of lubricant or grease within the body portion of the device, or in the path of the plunger so that when the plungers are manually shifted the lubricant or grease will be forced into the cup l.

lt is thought that the many advantagesv of' a filling device, in accordance with this in vention and for the purpose set forth, can be readily understood, and although the preferred embodiment of the invention is as illustrated and described, yet it is to be understood that changes. in the details of construction can be had which will fall within the light of the invention as claimed.

-What l claim is A portable lubricant or grease cup filler comprising a tubular body portion adapted to 'contain a body of lubricant or grease, a normally retracted spring controlled lubricant expelling plunger permanently arranged completely within said body portion intermediate the ends of the latter, a rotatable support extending through and journalled in said body portion, and a manually operated plunger shifting device connected eccentrically thereof to said means and having edge engagement with said plunger for shifting it to expel the lubricant, said body portion provided at one side with a lengthwise extending slot to constitute a clearance g for said device.

In testimony whereof, l affix my signature hereto.
